Back Vowel Phonemes

[Herb Stahlke]

This Northerner (SE MI, SW WI, N IN by age 21) has yet to see his
vowels as given by other Northerners, especially those of more
eastern extraction.  I have

dog = )
lost=)
horror=)
on=a
upon=)
water=)
wash=)
frog=)
watch=)
swatch=a
toss=)

but consistently /a/ before alveolar stops.  Unless I missed it,
I haven't seen different vowels in on and upon.  Swatch may be /a/
because I learned it later.
